Describe the major differences between the ecological niches of humans and cockroaches. Are these two species in competition? If so, how do they manage to
coexist?
The major differences between the ecological niches of humans and cockroaches depend on the functional role they play, the space they live, and the group (trophic level) they belong.
What is an Ecological niche?An ecological niche can be regarded as an area or set of environmental factors or the surroundings of an individual where they perform their functional role.
Humans being omnivores have a generalized niche where they particularly have many options to play a functional role (feeding habit).
Cockroaches play the role of decomposers which is also an important part of any ecosystem. Living organisms are interdependent, so they need each other in order to survive. Therefore, it is wrong to say that humans and cockroaches are in competition. Cockroaches unlike humans live in really dirty and dark places because in such conditions they easily find food. While humans take a rest in dark (night) and search for their food in the daytime.
Humans take fresh and cooked food, while cockroaches shred dead and decaying organic matter into smaller pieces so that it would be eaten by recycling bacteria.
Therefore, these two different species are not in direct competition and survive without affecting each other's ecological niche.

The overall charge of an atom is electrically neutral even though it contains Particles.
PLEASE HELP
Answer:
The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. Most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen.

6. What are three factors that affect the rate of diffusion? explain the effect of each factor.
7. What is the difference between simple diffusion and facilitated diffusion?
8. Compare (give similarities and differences) between diffusion and osmosis.
9. Why are diffusion and osmosis are important for living organisms?
Answer/Explanation:
[1] The three parts of the cell theory is all organisms are made of cells. Cells are the smallest unit of life and new cells arise from existing cells.
[2] The three structure that Eukaryotic and Prokaryotic cells have common is plasma membrane, ribosomes, cytoplasm, and DNA.
[3] The difference between prokaryotic cells and eukaryotic cells is prokaryotic cells has no nucleus while, eukaryotic cells have a nucleus.
[4] One example of a specialized animal cell is Muscle Cell. Muscle cells bring parts of the body closer together. They contain protein fibres that can contract when energy is available, making the cells shorter.
[5] One example of a specialized plant cell is cell wall. Cell wall shapes, supports, and protects the cell. It prevents the cell from absorbing too much water and bursting.
[6] The three factors that affect the rate of diffusion is temperature, concentration gradient, size of the molecule.
The size of the molecule: The smaller the molecule such as gas, the faster the rate of diffusion while the larger the molecules (liquid) the slower the rate of diffusionConcentration gradient: Diffusion takes place as long as there is a difference between the concentration gradient of substances across a barrier. The more is the concentration difference, the higher is the driving force, the faster the rate of diffusion. When the concentrations of the substance on either side of the barrier become equal, the diffusion stops.Temperature:The higher the temperature is, the faster the speed of diffusion. Temperature increases the K.E. (kinetic energy) of a molecule and it helps to move the molecule faster and hence the speed of diffusion increases.[7] The difference between simple diffusion and facilitated diffusion is simple diffusion, the movement of particles occurs along the direction of the concentration gradient. While in facilitated diffusion, the movement of molecules can occur both in direction and opposite of the concentration gradient.
[8] The similarities between diffusion and osmosis is they both particles move from an area of higher concentration to one of lower concentration. The difference between diffusion and osmosis is diffusion can occur in any mixture, including one that includes a semipermeable membrane, while osmosis always occurs across a semipermeable membrane.
[9] Diffusion and osmosis are important for living organisms because diffusion and osmosis both even forces inside cells and organisms as a total, expand water, nutrients and necessary chemicals from areas that contain a high concentration to areas that contain a low concentration.

Why are the nuclear reactions that occur in the center of the Sun critical to life on Earth?
a- life on earth depends on the energy and hydrogen released by the sun's nuclear reaction
b- life on earth depends on the heat and carbon released by the sun's nuclear reactions.
c- life on earth depends on the heat and electromagnetic radiation released by the sun's nuclear reactions.
d- life on earth depends on the energy and oxygen released by the sun's nuclear reactions.
Answer:
c
Explanation:
the earth needs the suns energy and heat
The reason why the nuclear reactions that occur in the center of the Sun are critical to life on Earth is: C. life on earth depends on the heat and electromagnetic radiation released by the sun's nuclear reactions.
A nuclear reaction can be defined as a type of chemical reaction in which the nucleus of an atom is transformed by either being joined (fusion) or split (fission) with the nucleus of another radioactive element's atom.
This ultimately implies that, a nuclear reaction is always accompanied with the release of energy.
On a related note, the Sun is typically characterized by nuclear reactions taking place at its center, which result in the release of radiant (heat) energy and electromagnetic radiation into the solar system.
Basically, this radiant (heat) energy and electromagnetic radiation are essential and very important to life because they are applicable and beneficial to humankind in several areas.
For example, radiant (heat) energy from the Sun in the morning, is a good source of vitamin.

Why does the Earth experience two high and two low tides each day?
Answer:
When the moon pulls on one side of Earth, the other side experiences high tide as well.
Explanation:
During the day, the moon revolves around Earth and when it does, it pulls on the oceans, causing high tide number one. But, when the moon pulls on one side of the Earth, the other side also bulges out, causing high tide number two. Think of this as a squishy ball. When you hold it with your index finger on the top and your thumb on the bottom and squeeze it, both sides of the ball bulge out. This is what happens to the Earth under the moon's gravitational pull.

Answer:
The Answer is A. the chemical inhibits the carrier potein for pyruvate in the mitochondrial inner membrane.
Explanation:
I just took the test so I know this is right
The statement regarding the effect of the chemical that is reasonable is that the chemical inhibits the carrier protein for pyruvate in the mitochondrial inner membrane. The correct option is A.
What is carrier protein?Carrier proteins bind the specific solute to be transported and then go through a series of conformational changes to move the bound solute across the membrane.
Carrier proteins bind specific solutes and transport them across the lipid bilayer by going through conformational changes that expose the solute-binding site on one side of the membrane and then the other.
Carrier proteins, like other membrane transport proteins, are found in lipid bilayer cell structures such as cell membranes, mitochondria, and chloroplasts.
A reasonable statement about the chemical's effect is that it inhibits the pyruvate carrier protein in the mitochondrial inner membrane.
Thus, the correct option is A.

What are the roles of the DNA, RNA Polymerase, mRNA, tRNA and ribosome in protein synthesis
Answer:
mRNA molecules carry the coding sequences for protein synthesis and are called transcripts. rRNA molecules form the core of a cell's ribosomes, the structures in which protein synthesis takes place. tRNA molecules carry amino acids to the ribosomes during protein synthesis. In eukaryotic cells, each class of RNA has its own polymerase, whereas in prokaryotic cells, a single RNA polymerase synthesizes the different class of RNA. Other types of RNA also exist but are not as well understood, although they appear to play regulatory roles in gene expression and also be involved in protection against invading viruses.
